Shaking an object with large coordinates.
This object is control by the user spaceship.
If 100000 - a bit.
1000000 at - it is impossible to control.
Why? How fix it?
You can’t use coordinates that large because of floating point imprecision. You can’t fix it, but you can work around it; there are several topics where this is already covered in depth so you can find them with a search.
